Abstract

A process is described for the more rapid regeneration of degree of whiteness or for the stabilisation of degree of whiteness of paper webs of different compositions, which have been subjected to a heat treatment of above 150 DEG C, for example in the manufacture of foam wallpapers, in which the paper web is exposed to high-energy ultra- violet radiation and/or high humidity or water immediately after the action of heat and before being rolled up. <IMAGE>
